A 29. 50

suitable spider 22 has arms 23 bolted as at 24 The shaft II is adapted to be rotated in any to said bosses 20 and it also has a sleeve bearing suitable way and for instance by a belt suitably 25 in which the shaft II is journaled. A nut driven, and tra-ined over apulley 6I keyed thereto 26 is threaded at 21 onto the tube 25 and beneath above the surface of the ground or closure 54. the same is an expansive coil spring 28 surround- When the pump is disposed Within casings 55 such as 3B, the Huid to be elevated or pumped from the casing enters the pumping chamber I5, through the ports or slots I9 and 2| and 49, and by the rotor I3, is discharged through the port I6 into the passage I'I, passing rapidly and forcibly up the inclined surface thereof through the passage 39 and expansive ring 34 into the upper portion of the casing 36, rising in the latter and discharging through the pipe 51. It will be realized that during use, gasket 35 is in intimate and pump-retaining contact with the inner Wall of the casing 36. However, when the pump is to be removed, applied or adjusted as to position, the element 58 is operated so as to retract the sleeve 29, links 30 and expansive ring 34 thus relieving the pressure and tension on the gasket 35 sulciently to facilitate the movement of the pump.

Various changes may be resorted to provided they fall Within the spirit and scope of the invention.

I claim as my invention:-

l. A pump of the class described having a vertical cylinder, an eccentric pumping chamber within said cylinder, a discharge passage extending generally longitudinally of the cylinder and communicating with said pumping chamber, a rotor operable in said pumping chamber, legs on said cylinder, a base plate across the cylinder having an entrance port for said pumping chamber, said base plate having legs engaging the rst mentioned legs, and means securing the legs of the cylinder and base plate together.

2. A pump of the class described having a vertical cylinder, an eccentric pumping chamber within said cylinder, a discharge passage eX- tending generally longitudinally of the cylinder and communicating with said pumping chamber, a rotor operable in said pumping chamber, a spider secured to the cylinder adjacent the top, said cylinder having a receiving port spaced from the spider, said spider having a sleeve in which the shaft of the rotor is journaled, bosses on the cylinder engaged by the spider, means securing the spider to the bosses, a plate resting on the upper end of the cylinder, and guided by said sleeve having a port in registry with said discharge passage, and coacting means between the plate and spider preventing rotation of the plate independently of the cylinder.

3. A pump of the class described having a casing, a vertical cylinder loperable therein, an eccentric pumping chamber within said cylinder, a discharge passage extending generally longitudinally of the cylinder and communicating with said pumping chamber, a rotor operable in said pumping chamber, a spider secured to the cylinder adjacent the top, said cylinder having a receiving port spaced from the spider, said spider having a sleeve in which the shaft of the rotor is journaled, bosses on the cylinder engaged by the spider, means securing the spider to the bosses, a plate resting on the upper end Aof the cylinder and guided by said sleeve having a port in registry with said discharge passage, coacting means between the plate and spider preventing rotation of the plate independently of the cylinder, a casing-engaging gasket above said plate, and means operatively supporting said gasket on said sleeve.

4. A pump of the class described having a casing, a vertical cylinder operable therein, an eccentric pumping chamber within said cylinder, a discharge passage extending generally longitudinally of the cylinder and communicating with said pumping chamber, a rotor operable in said pumping chamber, a spider secured to the cylinder adjacent the top, said cylinder having a receiving port spaced from the spider, said spider having a sleeve in which the shaft of the rotor is journaled, bosses on the cylinder engaged by the spider, means securing the spider to the bosses, a plate resting on the upper end of the cylinder and guided by said sleeve having a port in registry with said discharge passage, coacting means between the plate and spider preventing rotation of the plate independently of the cylinket and to which the links are pivoted, spring means urging downward movement of the collar, and means operable to slide the collar against the tension of the spring to permit retraction of the gasket.

5. A pump of the class describedhavingacasing, a vertical cylinder operable therein, an eccentric pumping chamber within said cylinder, a discharge passage extending generally longitudinally of the cylinder and communicating with said pumping chamber, a rotor operable in said pumping chamber, an operating shaft for the rotor, a bearing sleeve about said shaft connected to the cylinder, a plate resting on the upper end of the cylinder having a port in registry with the discharge passage of the cylinder, an expansive ring above the plate, a casing-engaging gasket mounted by said ring, a collar slidable on said sleeve, links pivoted to the sleeve and ring, spring means urging downward movement of the collar, and means operable to move the collar against the tension of the spring to permit retraction of the gasket.
